Would it be possible to add methods or properties to HTMLMediaElement to support scripted determination of client codec capabilities?
The supported codecs will no doubt change through the years, as the technology and the legal situation changes. I'd like to see determination of codec support (Vorbis, FLAC, Dirac, etc.) as well as container support (AVI, Ogg, etc.), and I think both can be done fairly simply by making available an array of supported MIME types. Implementors could be encouraged, via the standard, to expose both codecs and containers. -- Tim Starling Wikimedia Foundation
